arroba [Spanish]

From the Arabic rub'a. Symbol, @.

1

In Spain, at least as early as the 15th century – 20th century, units of liquid capacity. In the 20th century¹, the arroba menor, for cooking oil, approximately 12.563 liters (about 3.32 U.S. gallons). The arroba mayor, for wine, after the standard of Toledo, about 16.137 liters (about 4.263 U.S. gallons). As can be seen from the table below, not all Spanish provinces used the arroba of capacity; most of those that did not used the cántara. With the passage of time the two terms became synonymous, particularly in the Americas.

The Spanish unit led to various units of capacity in the Spanish-speaking world, ? – 21st centuries:

Bolivia See arroba in Bolivia.
Chile globe icon 40 liters in central Chile, 35.5 liters in the north. (Technical Factors..., 1972, page 132.)

Doursther (1840) says that at Valparaiso it was taken as 8¼ imperial gallons, or 37.48 liters.

La roua della lana di Valenza che libbre xxxvj fanno in Firenze libbre xxxvij e mezo intendi che ogni cantare chosì grosso chome soctile è roue iiij e ogni roua chosì grossa chome soctile è libbre xxiiij, la libbra è once xv, e la lib. grosse xviij once sì che la roua soctile è libbre trenta d'once dodici per libbra e la grossa è libbra trentasei d'once dodici per libbra.

The arroba of wool in Valencia of 36 libra makes in Florence 37½ libbre; note that each cantaro whether grosso or sottile is 4 arroba and each arroba whether grosso or sottile is 24 libra, the libra is 15 oncia, and the heavy libra 18 oncia, therefore the arroba sottile is 30 of the 12-oncia libra, and the arroba grosso is 36 of the 12-oncia libra.

Chiarini, 1481, as quoted in Edler, page 252. Compare Borlandi pages 40-41.

The 36-libra arroba was used for wool and the 30-libra arroba for grain. See Borlandi, page 40.
